The call quality is very good, both in GSM and UMTS networks.
2.) Does it switch between WiFi and 3G relatively easily?
The switch is very easy. You can configure the device to use 2G, 3G or 2G&3G. If configured to 2G&3G, the switch between these two networks happens within a few seconds - ca. 2 seconds.
